Ignorance, Or The Presence of Evil?

Long-term readers are aware of my frequently-updated post "The List".
There, I ask WHY entertainers are willing to alienate fully HALF the folks that might be interested in buying their produce by openly expressing their political views.
Do they have the right to do it? Certainly.
I, and millions before and after me have put our lives on the line for these misguided souls' right to openly illustrate their views (which, if allowed to come to fruition, would quickly put a stop to their ability to openly express political views).

The post immediately before this one is an example.
On "AXS TV" I watched a show called "The Big Interview", hosted by Dan Rather. The evil Mr. Rather was interviewing members of the band "Crosby, Stills, and Nash" individually and as a group.
During the individual David Crosby interview, Mr. Crosby profusely thanked Rather for his courage (HA!), in continuing to promote the truth. (!!!!)
Rather nodded and tried to act humble.

One of the very first things I did when I got home from Viet Nam was buy CS&N's first album. I played it on my new (bought while I was in Viet Nam) stereo system as loud as I could without incurring the wrath of neighbors.
I LOVE CS&N!!!

But they'll not get another dime of my hard-earned cash.
How did we get here?
